The purple and orange Halloween wide angle Flex-Change light is ideal for Halloween decorating.. The 5mm wide angle bulb is the brightest, most focused of our LED Halloween lights. The small wide angle bulb evenly distributes the LED light in all directions and produces the most consistent light output which is not affected by the angle from which the light is observed. These fully rectified sets are flicker-free and the Flex-Change technology allows the bulbs to be interchanged with any other Flex-Change set.
